I have to make a connecting flight etc.?

uming that all Airports do it the same... the Terminals change all the time. When you get off your flight, ask the attendant at the counter which one you need to go to, showing your ticket. That is, if they didn't already announce it to you on the flight, some do. It is a fairly smooth transition, as long as your first flight comes in on time. You should be fine! Don't sweat it! And don't be afraid to ask questions. That's what they are there for!
